16
Q

Axial Loading

A

each tooth should contact in such a manner that the forces of closure are directed through the long axis of the tooth

17
Q

What teeth are best suited to accept horizontal forces of occlusion?

A

CUSPIDS….

long, thick roots.

18
Q

What is canine guidance?

A

when canines disocclude the posterior teeth in lateral excursions.

19
Q

If canines are not positioned well or absent, what is the best occlusal scheme?

A

group function

20
Q

What is group function?

A

when several posterior teeth on the working side contact during excursions.FOUR points of contact

No contact on NON-Working side during excursions

No posterior contact during protrusive movements

21
Q

Most desirable contacts?

A

Canine plus premolars and the MB cusp of the FIRST MOLAR

22
Q

Mutually protected occlusion

A

Posterior teeth should contact slightly more heavily than anterior teeth in centric occlusion

23
Q

Thick tissue biotype

A

Low risk
Resistant to recession
Masks color
Scarring risk
